In January 1997, the Suwannee River Water Management District initiated a water level monitoring program at White Sulphur Springs near White Springs, Florida. The program's purpose was to assess the historical relationship between flow from the springhouse as a function of Floridan aquifer and Suwannee River levels. Anecdotal evidence indicates that discharge from White Sulphur Springs has decreased significantly over time. Springflow status was reviewed and data were analyzed to assess the quantity of springflow relative to aquifer head and river level. Regression analysis shows a strong relationship between differential head (Floridan aquifer elevation minus springpool elevation) and springflow when river conditions permit flow to occur. Using the above criteria, hindcasting was performed to April 1982, beginning date for continuous Floridan aquifer monitoring near the spring. The analysis indicates that between April 1982 and December 1996, the spring flowed roughly 40 percent of the time.
